[1/1 Formula]
Work: Calculate the value of equation (1/1^2)+(1/2^2)+(1/3^2)+(1/4^2)+(1/5^2)+(1/6^2) .
Question type: Mathematical calculation
Solution:
(1/1^2)+(1/2^2)+(1/3^2)+(1/4^2)+(1/5^2)+(1/6^2)
=1+(1/2^2)+(1/3^2)+(1/4^2)+(1/5^2)+(1/6^2)
=1+0.25+(1/3^2)+(1/4^2)+(1/5^2)+(1/6^2)
=1+0.25+0.111111+(1/4^2)+(1/5^2)+(1/6^2)
=1+0.25+0.111111+0.0625+(1/5^2)+(1/6^2)
=1+0.25+0.111111+0.0625+0.04+(1/6^2)
=1+0.25+0.111111+0.0625+0.04+0.027778
=1.25+0.111111+0.0625+0.04+0.027778
=1.361111+0.0625+0.04+0.027778
=1.423611+0.04+0.027778
=1.463611+0.027778
=1.491389
Answer:(1/1^2)+(1/2^2)+(1/3^2)+(1/4^2)+(1/5^2)+(1/6^2)=1.491389
